symmetric stretch造句

• The bands are for symmetric stretch, for asymmetric stretch, and for bending.
• Historically, the nitronium ion was detected by Raman spectroscopy, because its symmetric stretch is Raman-active but infrared-inactive.
• The symmetric stretch and bend are weak absorbers, but the antisymmetric stretch is strong and responsible for ozone being an important minor greenhouse gas.
• In some systems, such as silicon and germanium, the decay of the anti-symmetric stretch mode of interstitial oxygen involves the symmetric stretch mode with a strong isotope dependence.
• In some systems, such as silicon and germanium, the decay of the anti-symmetric stretch mode of interstitial oxygen involves the symmetric stretch mode with a strong isotope dependence.
• Ozone is a bent triatomic molecule with three vibrational modes : the symmetric stretch ( 1103.157 cm  " 1 ), bend ( 701.42 cm  " 1 ) and antisymmetric stretch ( 1042.096 cm  " 1 ).
• The symmetric stretch vibration mode has a wave number of 3213.1 cm  " 1 for the 3s 2 A 1'level and 3168 cm  " 1 for 3d 2 E " and 3254 cm  " 1 for 2p 2 A 2 ".
